-## Summary
-
-* The Factory Pattern is an Interface that defers the creation of the final object to a subclass.
-* The Factory pattern is about inserting another layer/abstraction between instantiating an object and where in your code it is actually used.
-* It is unknown what or how many objects will need to be created until runtime.
-* You want to localize knowledge of the specifics of instantiating a particular object to the subclass so that the client doesn't need to be concerned about the details.
-* You want to create an external framework, that an application can import/reference, and hide the details of the specifics involved in creating the final object/product.
-* The unique factor that defines the Factory pattern, is that your project now defers the creation of objects to the subclass that the factory had delegated it to.
